Static Bypass Switches

The Static Bypass Switch takes two sources of power at the input and monitors them continuously to provide the better of the two available powers to the electrical load connected at the output. One source is used as master and the other as slave. The load runs normally on the master and in any case of deviation of voltage and frequency from the defined threshold, the load instantly transfers to the slave source to provide uninterrupted supply to load. It is based on solid-state switch’s Silicon Controlled Rectifier (SCR), devices so it has no mechanically moving parts, thus requires minimal maintenance. It provides fast transfer time to protect the output load. The input sources can be a combination of UPS supply, mains supply or generator supply providing sinusoidal output. The Static Bypass Switches has high overload handling capability for safety.

Typical applications include servers, data centers, call centers, operation theatres or any other place which requires redundant power supply with fast transfer time so that load connected at the output does not experience any power break.

Su-Kam’s Single Phase and Three Phase Static Bypass Switch ensure high reliability and redundancy of power supply to the critical load.
